The Plastic of Plates, Plugs... and Pennies?
THE POTTI TEAM BLOG
The unending quest
for vintage jewelry knowledge has led me down some pretty strange paths, many
of them of surprising historical significance.
One of those amazing detours has led me to the first truly synthetic
plastic, usually referred to as Bakelite.
Pronounced
"bake-a-light," and spelled with a capital B, it was invented by Dr.
Leo Baekeland in 1907. Although he used a wood flour stabilizer, the
significant chemical bond that made it a plastic was formed between
formaldehyde and phenol, making it a synthetic plastic.

Bakelite, once it is formed, is heat resistant. It also does not conduct electricity. As Bakelite usage spread, it had electrical applications far and wide.
It was used as insulators, tubing, and housings. It was used for electrical plugs, socket plates, light switch plates, telephone housings and receivers, radio housings, and even camera housings.
It was used for common household objects - as pool (billiard) balls, utensil handles, toys for the children, chess and checkers pieces, dominoes and buttons. War time led to metal shortages, and Bakelite helped to make up for the shortage. The most fantastic use (in my mind at least) for which Bakelite was considered was as money. It was seriously considered as material for the 1943 U.S. penny. Steel was chosen instead, for the penny, at least.
Metal shortage in the jewelry industry was not solved
by the usage of steel, but one solution was indeed Bakelite. It was not the first plastic that the jewelry
industry had seen (there had been galalith and celluloid), but again, it was
the first synthetic plastic ever, and as such, the first the jewelry industry
had seen. It also proved to be more
durable than those which had gone before.
The term plastic jewelry makes many jewelry lovers
wince, but not if we are talking about Bakelite. Some Bakelite jewelry was quite classy - Coco
Channel sold Bakelite jewelry, and I can assure you it was not cheap! Vintage
jewelry need not bear a designer name to be of value when made of Bakelite; the
more elaborately carved and attractive pieces can be of surprising value.
To be factual, the patent on Bakelite ran out in 1927,
and the formaldehyde phenol polymer, used without the filler Baekeland had
used, emerged with differing names, and a variety of fillers. In spite of this, these pieces are known in
the jewelry business under the name Bakelite as an inclusive term.
How do you know if the vintage jewelry, or domino, or
button that you have is Bakelite? This
is one of those mysterious talents that seems to come only with use. Rubbing a Q-tip wet with 409 or Simichrome on
Bakelite is supposed to turn the Q-tip yellow, but these tests are not fool
proof. Some say that they do not work
with black Bakelite, and furthermore, if you do not carefully clean the
chemicals off after testing, they could damage some of the other early
plastics. Knowing Bakelite is a bit like
knowing many things in the antique and
vintage world - you have to handle it to know it.
Bakelite is typically heavier than other plastics, and
it has a distinct odor when heated. The
best vintage shoppers can rub a thumb briskly across a piece of Bakelite until
it is very warm, and smell that thumb, and detect it. It is described as an acrid chemistry lab
smell that gives many people a bit of a headache.
Chip and I have purchased a couple of pieces that were
sold as Bakelite, to test and get to know.
We have found a few that tested positive with either the Simichrome or
409, or both. But the smell test escaped
us.
I am sensitive
to lots of chemical smells, but I just could not develop the ability to sniff out Bakelite.
Some advice from our Captain Jesse was invaluable - he
suggested placing jewelry (obviously not a piece that could be harmed by the
moisture, such as one with rhinestones embedded in it) that had been heated by
running hot water, in a plastic bag for an hour. Chip did this, and got a good whiff of
Bakelite smell. Which is why he, at
least, can identify it for us now, even by the thumb rub method! This is good, since he is my buyer, after
all! Michele Davidson
